Rainbow Dash froze. Every muscle burned from the greatest sex of her life; her insides had been obliterated by Braeburn's unreal horse cock; she and the Appleloosan hayloft reeked of his cum. And Princess Celestia—judging by the hot, sticky pony love juice dripping from her forehoof—had enjoyed watching every second of it.
Rainbow bowed. “P-Princess Celestia, I can explain!”
Celestia shook her head. “There's no need to explain. You risked severe damage to your reproductive system, and thanks to you not acting like a proper mare and swallowing, you allowed Braeburn to ruin a perfectly good batch of hay, not to mention giving parts of this hayloft a new paint job. Oh yes, you've been...” She stuck the forehoof in her mouth, sucking on her own sweet fluids. As she rolled her eyes in contentment, her wings unfurled with a loud pomf! “... naughty. Very naughty.”
Rainbow gulped and would have taken a step back if she had not been already standing on the edge of the hayloft's opening. “Uh oh...”
“'Uh oh' indeed, my little pony,” Celestia said, waggling her eyebrows. “Oh yes, this calls for a drastic solution.”
Rainbow's eyes widened as Celestia slowly bore down on her. Her pussy ached, but it was the good kind of ache, like how she felt after a solid workout. “What solution?”
“Well...” Celestia licked her lips and eyed the semen-splattered Rainbow up and down. “Somepony needs to be taught proper etiquette; we can't have you and that stud of yours causing this much damage every time you two go at it, can we?” She bit her lip seductively. “Besides... I have not seen a stallion with that much equipment in centuries! Not even the Captain of the Royal Guard is so blessed.”
“Whoa, whoa, whoa!” Rainbow waved her forehooves in front of her. “Back up. Two things. You appoint your guards based on size? And what exactly are you implying with my coltfriend, huh?”
“Of course! Just because I'm Princess doesn't mean I don't have needs too. Why do you think I keep an all-stallion entourage? For protection?” Celestia giggled devilishly. “Oh no. I don't really need protection.” Leaning forward, Celestia snaked her tongue and lapped up one of the fresher splotches of cum on Rainbow's coat. “Delicious. Divine, even. Yes, it's decided. A wise pony once said, “You've gotta share, you've gotta care”. That applies to this situation quite perfectly, don't you think?”
Rainbow's ears drooped. “But Princess, you watched us! We're both pretty exhausted. There's no way—”
With blinding speed, Celestia locked her lips with Rainbow's. She only maintained their kiss for a split second, teasing the tip of Rainbow's tongue with hers before withdrawing about an inch and smiling sweetly. “Don't you worry about that. I've thought of everything. Tonight, I am feeling generous. That is why I will use my magic to scour this mess while you find a raincloud. Afterward, you shall return here, and we can all get some sleep. But once I finish raising the sun tomorrow, it is party time.”
Despite her best efforts, Rainbow's wings began to flare. “O-oh yeah? What if I just fly away and never come back?”
“Oh, please,” said Celestia. “That means you'd leave me alone with Braeburn. Believe me, when the Princess of Equestria presents, no stallion can refuse.”
Rainbow pawed at the ground. “But I like stallions, not mares!”
Celestia tutted and slowly shook her head. “Is that all you're worried about? When you've lived long enough, you'll come to understand how meaningless all this sexuality stuff is. You should be with who you want to be with. If you happen to want to be with a special stallion, that's great. If your special somepony is a mare, then that's fine too.” Her forehooves crept outward and wrapped Rainbow in a tight embrace. Celestia nuzzled her neck against Rainbow's. “I normally allow my students to learn for themselves, but I think it's time for a more hooves-on approach; tomorrow, between myself and Braeburn, you shall experience the best of both worlds.”
Scarlet patches appeared on Rainbow's cheeks. “All right. Fine.” She could not help but stare into Celestia's kind, loving, and sincere light cerulean eyes. Soon, Rainbow wore a broad smile that matched Celestia's.
“Now go,” said Celestia, copping a feel of Rainbow's fantastically firm filly flank. “The sooner you clean yourself up and get back, the sooner you can sleep for the night. Trust me, you'll need all the rest you can get.”
Rainbow nodded before taking off. It did not take her long to find what she sought. The cloud's cold water cleansed her coat of cum and sweat. Finally, her weary muscles began to relax. She sighed with contentment as she poked her head out and gazed at the sleeping Appleloosa far below.
“Princess Celestia was right... some sleep would sure feel good right about now.”
Not wanting to linger too long, she hopped atop the cloud, shook herself like a dog, and then sped back toward the hayloft. She returned to find it spotless, and Celestia gently snoring beside Braeburn. A pang of jealousy hit her stomach when she saw Celestia's left wing covering her lover like a feathery white blanket. Her feeling soon melted away like a piece of chocolate on Pinkie's tongue when she saw Celestia's right wing slightly unfurled, inviting Rainbow to rest beneath its warmth.
Nodding and smiling, Rainbow crept toward the waiting wing, taking care not to wake the slumbering ponies who would soon show her the time of her life. When she reached Celestia, she found a small bed of hay beneath the wing. Rainbow crawled under it, curled up into a ball, and nuzzled Celestia's side before closing her eyes and at last allowing herself to fall into sleep's welcoming embrace.
* * *
“Wake up, my little pony. You've got a big day ahead of you... in more ways than one.”
A gentle nibble on Rainbow's ear awoke her from her slumber. She blinked, and the room swam into focus. Celestia, free of her regal attire, stood over her, wearing both a smile and Braeburn's hat. Celestia winked before turning to Braeburn and whispering something in his ear.
Braeburn bolted upright. “What in the hay is going on here?”
“Braeburn, I can explain!”
Celestia guided Braeburn back to a lying position. She traced a forehoof in a circle on his chest. “Don't you worry, everything is taken care of. I saw what you did last night. I want some... of both of you.” She gave his snout a lick.
“Princess, I thought you only liked stallions!” said Rainbow.
Celestia turned to look at Rainbow. “Do you not remember the lesson I taught you last night? Indeed, a hooves-on approach is what is necessary today. Besides, I'm a Princess. Why should I have to choose?”
Braeburn tried to reclaim his hat from Celestia's head, but she winked at him and raised it out of his reach. “I... appreciate the offer, your highness, and you're most welcome here at AAAPPLELOOSA, but Rainbow Dash is my marefriend, my little bag of Skittles! I can't just cheat on her, especially not after our first date!”
“Well, my dear Rainbow Dash,” said Celestia, giving Rainbow a smile and a nod, “you are definitely most wise when it comes to finding a mate. He's so loyal, he may have been the Element of Loyalty had circumstances been different. Plus, he is quite... talented.”
Rainbow and Braeburn went red.
“But, Princess Celestia, why me?” said Braeburn.
Celestia's forehoof snaked down his chest until it found the large sheath that housed his impressive behemoth. “Several reasons. First, although I've seen significantly smaller members break larger and more experienced mares, Rainbow Dash has much to learn when it comes to handling such an instrument. Second, you need to learn some self-control; a well-disciplined stallion can last much longer. And third... while I have been with some enormous stallions in my time, it's been far too long since I've encountered one with your measurements. Nopony has made me scream in many a year.” She allowed a drop of drool to land on his chest. “I want you to make me scream.”
“Uh, hello? Princess? I'm still here, ya know,” said Rainbow, folding her forehooves. “He's my coltfriend, remember?”
“Very well,” said Celestia, pecking Braeburn on the lips before backpedaling and then sitting beside Rainbow. “Now Braeburn, I must know: How potent are you, on average? You reached no less than four climaxes last night—an impressive feat.”
Braeburn scratched his muzzle. “Two or three, dependin' on my mood. Why?”
“Oh, I just need to know what to expect before I begin our lessons.” Celestia tittered. “With that in mind, I think it is time we begin. Rainbow Dash, you shall kiss me and arouse me. At first, follow my lead, but you must not only show skill and proficiency, but unpredictability. Think you have what it takes?”
Staring at Celestia, Rainbow took a deep breath and flared her wings. “Are you kidding? I did the Sonic Rainboom twice and took everything Braeburn had to offer! I've got this no problem.”
“What about me?” said Braeburn.
Celestia eyed his crotch. “You will watch. But no touching! Us or yourself. It will not be easy, but you must exercise enough self-control not to coat us in that delicious seed of yours before the time is right, regardless of how... heated things become.” She tossed Braeburn's hat onto his crotch. “Don't worry—you'll get your action eventually.”
Braeburn humphed.
“Oh, don't be such a foal,” said Rainbow. “This'll be fun!”
“For you, maybe.”
Without warning, Celestia turned and kissed Rainbow. Her tongue effortlessly parted Rainbow's lips and probed into her mouth. Numbness spread through Rainbow's body as her senses focused only on her mouth and the skilled tongue cutting a waltz through it. She closed her eyes and leaned into Celestia's kiss, trying to match her tongue like an inexperienced dancer trying to copy the precise, measured steps of her instructor.
A thrill reverberated inside Rainbow. Braeburn was not a bad kisser by any means, but he paled in comparison to Celestia. She moaned, and would have begun thrashing her tongue inside Celestia's mouth if it were not for the gentle yet firm guidance of her teacher. Just when she had begun to grow accustomed to Celestia's movements, the Princess's tongue picked up its pace and played inside her much more wildly, but it retained its perfect control. Maybe mares were not so bad after all.
Rainbow moaned again, trying to keep pace. She felt a firm pair of forehooves pull her in closer, and she worked her muscles with everything she had, desperate not to allow Celestia to overwhelm her. The pleasure was so intense, Rainbow felt all thoughts slipping from her brain as more and more of her consciousness devoted itself to the kiss. She became aware of her marehood, hot and broiling, producing great amounts of her slick fluids in response to her peaking arousal. Celestia's forehoof began to tease it.
The air passing through Rainbow's nostrils grew ragged and erratic. Something finally snapped within her. She was no longer trying to harness and master her pleasure in order to satisfy Celestia; her pleasure had mastered her. With conscious thought no longer shackling her, Rainbow's tongue now moved of its own accord rather than trying to dance with Celestia's. It adopted its own pattern now, thrashing just as quickly, just as passionately, and even just as expertly, as Celestia's.
A soft moan escaped Celestia.
Rainbow pressed her advantage, and her forehooves darted forward, fondling and massaging every inch of Celestia they could reach. Not to be outdone, Celestia abandoned her tease, and instead slid in and out of Rainbow's cunny while the other rubbed on her flank. Jolted by the sudden increase in pleasure, Rainbow sent her forehooves south until they reached Celestia's flank.
Oh, and what a glorious flank it was. Far larger than the average pony's, it was soft and pillowy, yet firm and supple. A perfect combination. Rainbow grinded her hips against Celestia's hoof while she fondled and spanked Celestia's royal flank as hard as she could, eliciting a soft, feminine grunt from her partner each time. But neither mare lost their focus.
An all too familiar tingling flared across her foal garden's nerve endings before spreading through the rest of her. Her climax drew near. The pleasure signals her body sent her brain grew stronger and stronger, until they spurred Rainbow to plunge both forehooves into Celestia's pretty pony Princess pussy. Both mares broke their kiss and whinnied as they were rocked by a powerful simultaneous orgasm.
Rainbow's eyes rolled around in their sockets as the whirlwind of pleasure swept her away. Her nether lips clamped down on Celestia's forehoof as the Princess's did the same. With her tongue lolling from her mouth, Rainbow rode the pinnacle of her climax. She had no idea how much time had passed before she finally came down, and when her eyes regained focus, she saw Celestia, panting slightly, beaming down at her.
“Most excellent work, my student.” She turned to Braeburn. “And you, too. You displayed most impressive fortitude.”
“Ya—ya have no idea...”
When Rainbow looked at Braeburn, she almost burst out laughing. He sat in the same position he had before her make out session with Celestia, except he had his forehooves firmly lodged beneath his flank. His hat now hung atop his monstrous stallionhood, which now stood at its full twenty-two inches, with thick, bulging veins throbbing and pulsing with the enormous amount of blood needed to inflate such a behemoth. Pre-cum trailed down the mottled shaft in glistening streams.
After she took a deep breath, Celestia cleared her throat and nodded at Rainbow. “Now, before we proceed. Rainbow Dash, do you feel you can kiss like that any time you wish?” Rainbow nodded. “Superb. Braeburn, the time has come to reward your patience.” In one fluid motion, Celestia approached him, tucked her horn under his hat, and flicked upward. The hat sailed through the air, landing atop Rainbow's head. Celestia gave Braeburn's flaring and dripping cock head a peck akin to how she would kiss a newborn foal's forehead during a royal visit. “Lesson two shall begin immediately. I am going to suck you off, Braeburn. I will not stop until you explode. You must hold out as long as possible. Rainbow, you are to observe my technique and watch how I will not spill a drop.”
“Uh, Princess? Beggin' your pardon, but...” Braeburn patted his penis. “You did watch Rainbow and me, right? This big fella can pack quite a punch, especially if ya make me wait too much longer.”
Celestia ran her tongue from top to bottom before she nuzzled his overfull balls with her snout. “Oh, I am quite aware of the volume of your payload. In fact...” She rubbed her belly. “I'm counting on it.” She licked her lips and gazed hungrily at the pillar of turgid horse flesh towering before her.
“Uh, how's a pony supposed to breathe?” said Rainbow, scratching her head.
Celestia gave Braeburn's pride an appraising glance. “A good mare can find a way, even with something so thick.”
Rainbow groaned. “Is that all I get to do?”
“Don't be such a foal!” Braeburn giggled. “This'll be fun.”
Celestia winked at Rainbow. “Do not worry, Rainbow Dash. Once you feel you have observed enough...” She moved her tail to the side, revealing her dripping and winking nethers. “Help yourself.”
Rainbow blanched. “But... I like stallions!”
“Oh please,” said Celestia with a chuckle. “Would it really hurt so much to make an exception for little old me, just this once?”
“Stallions are hot.” Rainbow humphed. “They have nice hard bodies. And hard—” She glanced toward Braeburn's crotch and blushed. “You get the idea! Mares just don't do it for me!”
Celestia's marehood winked more rapidly. “What about that wonderful kiss we shared? You still prefer stallions, yet you seemed to enjoy it all the same.”
“Grah!” Rainbow pawed at the ground. “You do kinda have a hard body too... and nice wings. Still... I like stallions inside me, you know? A tongue just won't be the same, and I should be doing the sucking.” She jerked her head upward and snorted.
“C'mon, Skittles, it's not like everypony in all of AAAPPLELOOSA is gonna know! It'll just be between us three,” said Braeburn.
Rainbow's face scrunched. “Oh... but... well... she is offering, and she did want me to learn about this sorta thing...” She shuddered as Celestia's tail began snaking around her neck, the tip tickling her muzzle. “Fine, but it's just to learn, okay?”
Celestia moved her tail back into a more modest position. “Excellent! But first, you must observe.” She opened wide, licked Braeburn's flat cock head, and effortlessly popped it into her mouth.
Rainbow's jaw dropped open as she watched Celestia devour inch after inch of Braeburn's meat, creating a visible outline in her throat as she took more and more.
“Oooooh, Princess, yer throat is so tight! It's amazing!” Braeburn's forehooves rested on Celestia's head and pressed down. “Yeah, take it all the way to the base!”
“I took over half of it in my mouth,” said Rainbow, leveling her head with Celestia's. “Think you can do better?”
Celestia looked at her, but her expression did not change as she methodically took more. A look of half admiration, half jealousy spread across Rainbow's face when she saw Celestia surpass her mark. Although a good eight inches or more of Braeburn's blessing remained, Celestia showed no signs of stopping. Rainbow looked away and humphed before stalking behind Celestia. Both mares' wings stood at attention as Rainbow placed her muzzle against Celestia's begging vagina. It smelled like tuna and peaches.
Grabbing Celestia's flank, Rainbow dove in. She tasted as delicious as she smelled. Using her newfound tongue techniques, she explored every inch of Celestia's spacious love tunnel. She stuck her muzzle in as far as it would go, and Celestia's marvelous mare mating musk filled her nostrils. Rainbow continued to lap up every drop of the delectable juice that Celestia's tightening marehood churned out.
When she had had her fill, Rainbow withdrew her muzzle, licked it, and smacked her lips. Giving a feral grin that nopony could see, she spanked Celestia's flank with the sound of a thunderclap that drowned out the loud slurping and gurgling that filled the hayloft. A red reminder of Rainbow's randiness glowed upon Celestia's right flank and her sun mark.
“She said to be unpredictable,” Rainbow muttered as she stalked toward Braeburn, who was too absorbed in absolute pleasure to notice. “Time to give her what she wished for.”
Rainbow eyed Celestia's spiraled horn. It was quite long and exceptionally thick at the base, but nothing she could not handle—not after being with the behemoth Braeburn the night before. Noticing Celestia only had a few more inches of Braeburn left, Rainbow made up her mind. She licked the whole length of Celestia's horn, starting from the base and working her way up until she sucked on the tip. It took a couple more full passes before she was satisfied.
With one forehoof swirling around her tingling treasure and another adjusting Braeburn's hat on her head, Rainbow flew a few feet in the air. She carefully lined up Celestia's horn tip with her quim, then carefully lowered herself onto it. Thankfully, Celestia's horn was blunt, so Rainbow did not risk injury impaling herself on it. Her nether lips kissed the royal shaft as passionately as she had kissed Celestia, causing her to bite her lip as she allowed it to penetrate her.
Rainbow's moans and grunts mingled with Celestia's gulping and sucking as she bottomed out on the horn. It was then Rainbow realized just how hard Celestia sucked her lover's meat. Celestia's head bobbed up and down in subtle, rapid motions, while her throat constantly constricted and slackened, just enough to allow her to breathe and introduce Braeburn to a whole new level of pleasure. Rainbow took mental notes before staring down at her lover.
Rainbow cupped Braeburn's muzzle in her forehooves, directing it toward hers. She leaned forward and kissed him. Already on the brink of losing herself to ecstasy, it took little effort for Rainbow to kiss her coltfriend in a way that would make Celestia proud. She was pleased to note that Braeburn began whimpering as soon as she worked her tongue magic in his mouth. Braeburn could only loll his tongue around Rainbow's, but she did not care; she rocked her hips, bucking against Celestia's head in time with its movements, and did her best to guide Braeburn's tongue as Celestia did for her.
Soon, Braeburn's forehooves found themselves on Rainbow's flank as she rode Celestia. As her lover's tongue began to adapt to and reciprocate with her passionate kiss, Rainbow knew she could not last much longer. She bucked harder and faster, determined to outlast Braeburn. But this was one competition she did not win. She made one long, continuous moan inside his mouth, and every muscle tensed up. Snapping her head back, Rainbow whinnied and came, drenching Celestia's head in her filly fluid. Rainbow stared down at Braeburn, whose face scrunched as red patches blossomed on his cheeks.
“Ooooh, Rainbow, oh, Celestia, I'm gonna cum!” Braeburn clamped his eyes shut. “Aaaah, it's gonna be huge!” He gritted his teeth and spanked both of Rainbow's flanks hard.
“This I gotta see!” Rainbow, having recovered enough from her latest orgasm, hopped off Celestia with great difficulty. Without taking the time to notice her own juices dropping from Celestia's horn, she gazed at Celestia's mouth, which was firmly pressed against Braeburn's crotch, just in time to see Braeburn's swollen testicles hop up against his body.
Although the entirety of Braeburn's shaft was buried inside Celestia's mouth, Rainbow saw his first shot clearly speeding down its pipe from the bulge in Celestia's throat. Celestia closed her eyes with contentment as load after load splattered inside her stomach. Rainbow sat on the ground, her wings throbbing from arousal, staring in awe at the throbbing and pulsing outline of Braeburn's enormous equine erection ejaculating inside the Sun Princess of Equestria's gullet.
A whole minute had passed, and Braeburn showed no signs of slowing down. Rainbow was in total disbelief. She would have definitely had to dislodge his stallionhood from her throat by now to prevent herself from drowning, yet Celestia continued to carnivorously consume his creamy colt-creating chowder, so much so that her belly began to swell from the sheer volume of the stuff inside it. Celestia's eyes widened as Braeburn kept pumping her full of splooge, until he finally thrust his hips and let out a long gasp as his horsegasm petered out.
Celestia meticulously raised her head, removing Braeburn's still-stiff pride from her mouth. When it could finally breathe again, she gave the head another kiss. “That was impressive. Up there with the largest loads I have ever seen, I daresay. And you're harder than ever.” She smacked her lips. “Most excellent indeed. Rainbow Dash, did you learn the technique?” A soft belch escaped her as she rubbed her belly gingerly. “I think it will be a little while before I can do that again.”
“I—I think so... but how did you swallow it all?”
“Diligence, my dear Rainbow Dash, diligence.” Celestia clapped Rainbow on the shoulder. “Now it is your turn, my student. Also, I must say, you are quite adept at horn-riding. You are learning well.”
Rainbow blushed. “Yeah, I think I'm ready. Are you sure I can swallow that much if I just put my mind to it?”
Celestia nodded.
“Uh, ladies?” Braeburn ran his forehooves along his saliva-coated shaft. “Before y'all make me go off again, can... can ya do that thing Rainbow did? With yer wings?”
Rainbow and Celestia exchanged glances and grins.
“Ooh, you want a wingjob, huh?” Rainbow flexed her wings and kissed Celestia, whose mouth strongly smelled of Braeburn's musk. “What do you say, Princess? Think we can make that happen?”
Celestia returned Rainbow's kiss. “Yes, Rainbow Dash, I think we most certainly can.”
Whooping, Braeburn punched the air before lying flat on his back and placing his cock in a vertical position. Celestia and Rainbow wrapped their wings around it and began to stroke. Rainbow giggled as she and Celestia made Braeburn whimper with their wing movements. White feathers intertwined with cyan as they moved up and down in tandem, neither mare setting the pace. Looking into Celestia's eyes, Rainbow began pleasuring herself with one forehoof while gently massaging Braeburn's balls with the other, speeding the recreation of their scrumptious stallion semen supply.
Braeburn gave a loud snort. “This is what heaven must be like.”
“No,” said Celestia, biting her lip. “This is what heaven is like.” She bent down and started kissing Rainbow.
Rainbow's mouth ached from its previous workouts, so she opted for a slower pace. Celestia must have sensed this, as she allowed Rainbow to keep things nice and relaxed. The taste of Celestia's saliva left a pleasant tingling in Rainbow's mouth; it had a strong aftertaste of Braeburn's shaft and spunk, almost like an appetizer for the impending feast. Once she fell into a rhythm with her wing, tongue, and forehooves, Rainbow entered a trance-like state where gradually mounting pleasure was the only thing she felt.
“Unf, this feels so good, I don't know how much longer I can last!” said Braeburn some minutes later, causing Rainbow to break her kiss.
Celestia removed her wing. “You had better get sucking. I do not expect you to take the whole thing, but you must certainly not spill a drop. You have witnessed what that delightful abomination is capable of—I doubt either of you would want to have to clean that up after every little quickie.”
Rainbow nodded. She was prepared. Taking a deep breath, she opened wide and popped the flared head in with minimal difficulty. She found it much easier the second time around. A grunt and a swift dip of the head later, and Braeburn's poner penetrated her throat. Remembering Celestia's technique, she sucked as hard as she could with not only her mouth, but her throat as well, creating a similar slurping sound to Celestia's. She sucked and sucked until her muscles were forced to slacken. When they did, a few precious breaths of air entered her lungs despite the incredibly thick obstruction in her throat.
Feeling quite proud, Rainbow took her lover deeper and deeper while making sure not to take him too quickly. Just as she began to grow used to it, something soft entered her trembling nethers. No sooner had she realized it was Celestia's muzzle than the Princess's tongue began to lash against her tight pink walls. Rainbow had to struggle to maintain her concentration; Celestia's tongue took no prisoners, and when it found her g-spot, it danced on it mercilessly.
Rainbow would not allow herself to be outdone or thrown off by the elder mare. After a brief pause, she harnessed the incredible sensations of Celestia-given cunnilingus to spur her onward to taking greater lengths of Braeburn's stallionhood. She stroked it up and down as she greedily gobbled it, slurping for all she was worth. When she passed the ring signaling the halfway point, Rainbow realized that she did not need to stop.
Braeburn's balls appeared as twin shining beacons for her. Rainbow's heart quickened as the pulse of her lover's rod increased along with the volume of his whimpering and grunting. She did not have much time, and the home stretch was proving difficult. Cursing her relatively small size, she took as much of him as her body would allow, but she could simply not bottom out. Having only a few inches of meat left, Rainbow directed her forehooves to his huge testicles once again, giving them a massage worthy of the spa twins.
“Rainbow! Rainbow, yer so good, I'm gonna—I'm gonna!”
Three things happened at once. Rainbow braced herself; Celestia grabbed her flanks and buried her muzzle in as far as it would go, lashing her tongue around inside Rainbow's honey pot; and Braeburn came. Rainbow's eyes bulged as the first enormous shot geysered forth into her waiting stomach. Wrapping her forelegs around Braeburn, Rainbow put her faith in Celestia's wisdom that she could weather the storm and survive the semen-spewing leviathan writhing fathoms deep inside her.
Rainbow could do nothing but stand there and take everything the bucking Braeburn could throw at her. Her eyes watered as her overfull stomach began to stretch and expand from the ludicrous salvos of stallion sperm spattering from Braeburn's spitting sex stick. The warring pleasures of Braeburn's spraying horse cock on one end and Celestia's licking on the other threatened to tear Rainbow apart. But she kept calm and sucked on for what felt like hours.
After a few more shots, Braeburn sighed with relief. When Rainbow made sure he had finished, she cautiously raised herself off his rigid member. It took nearly a full thirty seconds before she managed to pop the head out of her mouth. Braeburn looked up at her, beaming.
“Well done, my student, well done,” said Celestia, wiping the rainbow juice from her muzzle and licking the hoof she used. “I did not expect you to take it all on your first try. Do you feel all right?”
Rainbow was halfway through nodding before she held a forehoof to her muzzle. Her stomach leapt up, and she retched. Thanks to her tightly pursed lips, her cheeks ballooned outward until she could hold back no longer. She coughed and a remarkable amount of semen spilled from her mouth, forming a large pool on the floor. Another cough preceded a second wave of the fluid before she recovered, wiping her muzzle. “Yeah, I'm fine.”
Braeburn whistled. “Wow, I really came a lot.”
Celestia nuzzled Rainbow and smiled sweetly at Braeburn. “You sure did. A testament to Rainbow Dash's coital acumen.”
“So, what next?” said Rainbow, suppressing another cough.
Celestia turned and presented herself to Braeburn. “The big finish.”
Rainbow pouted. “What about me?”
Using her wing, Celestia steered Rainbow around until she too displayed her treasure for her lover. “Patience. He will alternate between us until he is spent. What say you, Braeburn? Think you have another volley?”
Braeburn placed a forehoof on both mares' flanks. “Oh, yeah.”
“Then let us begin.” Celestia pecked Rainbow on the lips.
Rather than picking either of his lovers, Braeburn stuck his stallionhood between the two and pressed their flanks together to create a sort of hot dog, with the mares as the buns and his cock as the meat. When Rainbow and Celestia clued into his plan, they pressed their bodies together. No longer needing to use his forehooves to guide them, he stuck one in each pussy before he began humping.
With Braeburn's cock rubbing against her body and her maregina pleasured by his forehoof, Rainbow held Celestia close and kissed her. The physics-defying blowjob she had recently administered left her throat sore and aching, but it had given her tongue valuable time to recuperate. Rainbow used her renewed vigour well enough to coax a startled moan from Celestia as she passionately and relentlessly assaulted her mouth.
As Celestia kissed back, matching Rainbow's fervour, loud slaps filled the air. Braeburn had switched from dividing his attention evenly to going balls deep into the Princess. Feeling jealous, Rainbow redoubled her efforts. Celestia began to waver. Rainbow was in disbelief when she realized Celestia was nearing her breaking point. Celestia broke their kiss with a great whinny that reverberated off the hayloft's walls and probably echoed through all of Appleloosa.
“Oh, Braeburn, you are so huge!” Celestia's hooves scrabbled against the ground as she sank. “You're so—so—” She closed her eyes and screamed.
“Yeehaw!” said Braeburn, pulling out and sliding his hungry cock head into Rainbow's tight cunny.
Rainbow then realized why Celestia now lay on the floor wheezing with her eyes spinning. Her body had forgotten the sheer magnitude of Braeburn, who slid over three-quarters of himself into her. Rainbow's legs buckled almost instantly, but Braeburn held her upright with his penis alone. Each time he thrust, he came closer to hilting in her. Fortunately, the painful breaking-in process had been completed the night before, so it was only a matter of time before her body granted the whole thing entry.
A squeal from Rainbow and a slap of Braeburn's balls against her crotch heralded his full penetration. Resting his forehooves on Rainbow's flanks, Braeburn went to town on her, humping with everything he had. Rainbow found herself in an endless stream of orgasms; when one climax faded, another more powerful one took its place. A near-comatose state fogged her endorphin-overloaded brain as their interhorse reached levels she did not think were possible—not a single nerve of hers was not flaring to its near-breaking point.
“Rainbow, yer just so tight, I don't think I can take it anymore!” Braeburn's cry came strained.
“Give—give me some, please,” said Celestia, scrambling back to her hooves. “Not all of it—just give me some—and then finish inside her.”
Braeburn pulled out with a grunt. “Yer wish is my command, yer highness.”
Rainbow looked behind her just in time to hear Braeburn whinny and climax. Although his phallus fired on all cylinders, he still humped Celestia in enormous thrusts, making the Princess moan with sheer ecstasy. Just when Rainbow began to wonder if there was any spunk left for her, Braeburn pulled out of Celestia quick as a flash, and managed to stuff himself halfway in before he fired his next shot.
While Braeburn had ejaculated inside Celestia for nearly a minute, Rainbow was not left wanting. He mated with her with just as much vigour as he had given Celestia while more and more huge volleys of his seed coated Rainbow's insides. Rainbow felt herself overfull with cum once again. As she grew afraid that she might pop, Braeburn sank himself into her with one final thrust as his summer sausage finally softened.
Braeburn and Rainbow Dash lay panting and gasping in a heap, semen oozing from her mauled nethers. Neither could move a muscle due to their exhaustion. Rainbow's eyelids felt like they were made of lead as her vision began to glaze over. She smiled, allowing simple bliss to embrace her and her lover. Celestia was the first to stand up, looking down at Rainbow and grinning.
Celestia's coat began to ripple. Rainbow gasped, as it looked like Celestia melted before her eyes. More of the Princess deflated, like a balloon slowly losing its air, as Celestia's face crumpled, and her neck collapsed. The process lasted a few seconds until what was left of Celestia lay in a flat heap on the floor.
Pinkie Pie stepped forward from the remnants of her Princess Celestia costume. “Gotcha!” she said.
